MSPM0H3216: RTC clock accuracy and power mode

Part Number: MSPM0H3216


Hi,

My customer would like to use RTC calender information to perform timestamp for their data log.
In my understanding, in case of MSP430, internal clock for RTC can be applied when device is "deepsleep" mode which is most low power mode setting.
According to datasheet of H3216, this device also have similar low-power mode.
When I checked following figure, I understand that "STANDBY1" is lowest power down mode and RTC function is enabled even though device enter this low power mode.

So, user can operate RTC function by using internal oscillator (32.768kHz) if they exit active mode(like "RUN" mode).
Then, I have following questions.

Q1. According to datasheet, worst spec of internal LFOSC accuracy is 5% under maximum operating temp.
Is it same meaning that internal RTC accuracy is 50000ppm ?

Best Regards,
